In recent years, many attempts are being made to develop new lubrication coatings for cold forging. In general, an alternative coating is designed based on the results of the evaluation methods that simulate the frictional condition of cold forging. Various evaluation methods have been proposed and used to design an alternative coating according to the processing purpose. However a lot of parts are manufactured by the multistage forging machine such as parts forming machine, complex shape being produced recently by combined processing. A lubrication coating in such an environment is exposed to repeatedly in a variety of processing modes, and received serious damage. At present the performance of an alternative coating isn’t enough to satisfy needs of market in such a multistep forging. Development of lubricant that can satisfy such demands needs a new evaluation method. This comes the purpose of this study. An newly devised tribometer consists of an ironing process after upsetting process. We designed this test method by using finite element(FE) analysis. In upsetting, damage to the lubrication coating is given by the expansion of free surface. In ironing, the performance of lubrication coating destroyed by upsetting is evaluated. By using the upsetting-ironing type tribometer, the lubrication performance under a large surface expansion and a high pressure can be evaluated. In addition, the degree of coating damage can be adjusted by changing upset ratio and height of billet. The difference in the lubrication performance of the bonderised and the prototype alternative coating was examined by this evaluation method.

While TOPSIS is a widely used evaluation method, it lacks evaluation from the perspective of indicator coordination. Based on the analysis of TOPSIS evaluation methods, this paper proposes a new assessment method, coordinated TOPSIS, which takes into account the advantages of TOPSIS evaluation methods and the coordination level of evaluation indicators. Taking the robotics academic journals as an example, the TOPSIS evaluation and the coordinated TOPSIS evaluation results are compared. The research shows that the weights of the coordinated TOPSIS method can be manually adjusted according to the purpose of evaluation and have a good flexibility; the TOPSIS evaluation results and coordinated TOPSIS evaluation results have a high degree of correlation, but the difference from the perspective of the ranking is big; the coordinated TOPSIS is very suitable for evaluation field that needs to consider the coordinated development, and it can be replicated.

Japanese traditional cuisine “Washoku” was registered as one of the intangible cultural heritages in December 2013. “Washoku” contains and requires large amount of sugar, therefore, sugar is an important seasoning in taste. Japanese have been using many kinds of sugar such as Granulated sugar, White soft sugar, Brown soft sugar, White crystal sugar and Light brown crystal sugar according to application, for both home cooking and processed foods. Mitsui Sugar is focusing on the difference in taste of sugars to develop new attractive sugar products. With a sensory evaluation method, trained panelists could recognize the difference between these sugars though it is quite difficult to explain. Therefore one attempte624-627d to detect the taste difference in these sugars by using a taste sensing system. The system comes with a human taste model membrane and can analyze the density and balance of several tastes such as sweetness, bitterness, umami** and saltiness. The accuracy of the sensing system was evaluated by comparing the results against the sensory evaluation method by trained panelists. The sensing system was able to detect the difference in taste of Japanese sugars, and the results from the sensing system seemed to match with the ones from the sensory evaluation method. The results were plotted on a taste map. This map will be helpful not only in showing the difference between the sugars, but also in explaining the characteristics of the new products.

Facing climate risks has become a common problem for mankind and a topic of great importance for the Chinese government. To thoroughly implement the overall requirements for the construction of an ecological civilization and effectively improve the capacity of cities to adapt to climate change, China launched the pilot construction of “Climate Resilient Cities” in 2017. In this paper, 16 prefecture level cities in Anhui Province of China were selected as the research objects, and the multi-level grey system evaluation method was used to measure the climate resilience of these regions. We used the difference in differences method to evaluate the effect of the pilot policy of “Climate Resilient Cities.” The pilot policies of the “Climate Resilient Cities” showed a significant contribution to the regional climate resilience, and, after isolating the impact of other factors on the regional climate resilience, the pilot policies of the “Climate Resilient Cities” increased the climate resilience of the pilot cities by four percentage points. The pilot policies of the “Climate Resilient Cities” had a significant contribution to the urban infrastructure development and ecological space optimization, as well as non-significant impacts to the urban water security, emergency management capacity-building, and science and technology innovation initiatives.

The construction project bidding is a feasible method in engineering transactions and the main competition form of the construction activities under the conditions of the market economy. The bid assessment is an important link of bidding, and whether bid evaluation method is scientific or not, is directly related to the success of the tender. In the engineering construction field, at present the current commonly used evaluation methods are the comprehensive evaluation method and the lowest bidding price evaluation method. Based on fuzzy set theory and multi-objective people decision theory, we introduce fuzzy multi-objective people decision-making evaluation methods. And conducting research to put forward the evaluation index and weight method to determine the bidding decision model. Finally we apply it to actual case to make out the more standardized and scientific bidding evaluation method.

Assessment of the structure durability of concrete bridge in service is crucial for determining whether their service performance is meeting the design requirements or not. In this paper we classify the whole structure of bridge into two levels, i.e.bridge structure and bridge components. A two-level-multi-index model for evaluating the durability of concrete bridges in service is established based on the dependent functions of various factors, in which the dependent functions are chosen in accordance with the difference of various factors affecting the deterioration of durability of components. In this model, the durability of the bridge is divided into five different fuzzy levels: intact, disrepaired, damaged, severely damaged, and dangerous. Finally, based on fuzzy mathematics theory, the durability level of a bridge in practice is evaluated by using the maximum subordination principle.

For the problems of few current defogging effect evaluation methods and limited evaluation methods, it proposes an image clarity effect evaluation method: the method combined with relative contrast and edge similarity. This is because: the contrast degree of fog image and non-fog image is obviously different. While improving image contrast degree, it should also try to make the edge structure of recovery image and reduced image consistent to prevent the recovery image from distorting. The experiment proves that this method can effectively evaluate the clarity effect of each algorithm, and the evaluation result and the subjective feelings of the human eyes are consistent. Compared with the existing evaluation methods, it obtains overall evaluation conclusion and also has a good practicability and reliability.
